Title: Film lagging exposed roof in mechanised faces - using perforated or porous and gas-permeable material to allow gas or air to escape
Inventor: POLLER DIETER ING GRAD
IPC: E21D19/02
Filed: 1975-02-25
Abstract: Lagging the exposed roof with film in mechanised coal-mining operations is to hold the sensitive roof beds and prevent flaking and falls which give rise to dust and other dangers. The film is normally dispensed from a roll and bonded to the roof with the aid of an adhesive containing a solvent and backed up by a pressure roller to press it to the exposed roof surface. The film to be used now is to be perforated right the way across, or else be designed as a porous and gas-permeable material. Typically the film used are thermo plastics such as polyolefine, polyvinylchloride or polyester resin material. The aim of the perforations is to allow any air or gas bubbles forming between the film and roof to escape without rupturing the film.

Title: Fitted bed sheet of simplified design - short rectangular strips sewn at short sides to complete border
Inventor: REITER HERBERT
IPC: A47G9/02
Filed: 1975-05-16
Abstract: The sheet is made by folding the long sides (2, 3) of the cloth over, and sewing the ends down, then sewing short rectangular strips (6, 7) at the short sides of the cloth, to complete a border of uniform width all round. Tapes are sewn across the seams (8) in the border, to strengthen them. The finished sheet has required only the simplest of cutting and sewing, and, being flat, it is easy to launder, especially to mangle. Fitting it on the mattress leaves its corners sticking out in triangles, but these can be neatened by tucking them down beside the mattress after they have been turned inside out.

Title: Multi-way valve with tubular piston - has small area of piston exposed to pressure to reduce actuating force
Inventor: MUELLER GOTTFRIED
IPC: F16K11/02
Filed: 1975-06-26
Abstract: A multi-way valve has a cylindrical body with connections (1, 2) at each end. The valve seat (7) is mounted centrally in the body with a flow path for the fluid around the outside of the seat. The tubular piston (10) is supported in sealed guides. A control valve (27) can admit air or oil to one side or other of the piston through ports (16, 17). The tubular piston (10) can thus be pushed on to the seat (7) to close the valve. The use of a tubular piston reduces the weight of the moving parts and also reduces the area exposed to the pressure of the medium flowing through the valve. This results in a reduced actuating force.

Title: Non-mechanical electrostatic printer - has charge image formed on intermediary band which moves in direction of recording paper
Inventor: UNGER HEINRICH
IPC: B41J2/41
Filed: 1975-08-12
Abstract: Non-mechanical printer operates electrostically or electrographically whereby the charge image of the information to be printed is formed on an intermediary carrier. The image is developed with the aid of a toner. The intermediary carrier comprises a band which moves at a constant speed in the direction of the line which is to be printed on the recording surface. This latter surface (SP) and the intermediary carrier (ZT) move between a first electrode (EP) and a guide plae (FP) in the image transfer unit (UR). An air gap (LS) is thereby maintained between the band (ZT) and the recording surface (SP) so that the toner image can be transferred from the band to the surface by applying a voltage impulse to the electrode (EP).

Title: Automatic channel error compensation method - is used for multiple channel direction finding receivers
Inventor: FLIEGE HANS-JOACHIM DIPL ING
IPC: G01S3/02
Filed: 1975-09-18
Abstract: In case when only one compensation of phase erros is to be carried out, phases of output voltages of all channels except one are split, so that they differ by 90 deg., and the two voltages of each pair are separately multiplied by the channel output voltage which has not been converted. They are passed through a filter and a latching circuit, multiplied by themselves and added in pairs to form a sum voltage. If in addition amplitude errors are to be compensated, either both voltages of each pair, or their sum voltage are in addition divided by the square of one or both voltages of the same pair, and passed through a filter and latching circuit. Or each of the two voltages in a pair is squared, passed through a filter and latching circuit and multiplied by both voltages of each other pair, or by their sum, and by the non-converted channel output voltage.

Title: Sludge collector and light liq. separator - from sewage with two tanks in single housing and cover
Inventor: DIEFENBACH GUENTER
IPC: B01D17/00
Filed: 1976-02-13
Abstract: Plant, for the sepn. of settled material and light liqs. from waste water and sewage, comprises a sludge collector and a separator for the light liqs; they form a compact installation in a common housing, with a cover. The water to be purified arrives at the inlet; material which settles out is deposited in the collector whilst the liq. passes over the overflow and under the partition into the separator. Here the associated light materials, such as oil, petrol, fats, etc. float to the surface while the water passes under the partition to the outlet. when the sepd. materials pile up sufficiently to be evacuated, a pump is brought into action; the light liqs. are withdrawn through one pipe and the sludge by another pipe. The layer of floating material is first broken up by the prodn. of a powerful, horizontal jet by the injector, making use of recycled water. After the evacuation, the collector and the separator are washed by water. The sepd. materials do not need to be evacuated by hand but can be sucked out by a pump when necessary or at regular intervals; this can be followed by a complementary washing.
Patent DE-2607343-A1 (DE)
Title: Drive system for lubricating oil pump and water cooling pump - in which each pump has own engine speed independent drive unit
Inventor: MOLL HANS HEINRICH DR ING
IPC: F01P7/16
Filed: 1976-02-23
Abstract: Engine lubrication oil pump and water cooling pump are driven by separate motors independent of engine revolution speed. Engine lubrication takes place before engine is started and so reduces wear. The oil pump continues to run for a predetermined period after the engine has been switched off to lead heat away from the bearings. The oil pump speed is controlled by the main bearing oil pressure. A three way tap is fitted for oil change purposes. The water circulation pump is regulated by a heat sensor fitted in the cylinder head. A conventional thermostat would not be required since the pump would not be actuated until working temperature had been reached. The water pump continues to run after the engine has been switched off to avoid the formation of air locks. The radiator fan uses the same motor which may be either electric or hydraulic.
